Average (±SD) of every HRV parameter (column one) when supine (the upper part of the table) and standing (the lower part of the table) in each group (column two) for all the participant (column three) in PRE-tests (column four) and POST-tests (column five). The F and P-values of the ANOVA were reported for the main effect of Group (column six and seven), Session effect (column eight and nine), and Group×Session interaction effect (column ten and eleven). For a sake of clarity, parameters with significant statistical Group×Session interaction were reported with bold characters and the interaction effect analyses are detailed in the text. p. > 0,05; * p. < 0,005; ** p. < 0,01; *** p. < 0,001.
